That _was_ from systemtap.log.  That was as complete as the log
gets for this test.  Is there a way to get it to put more in the log?

(Systemtap.sum is nearly the same.  It is only missing the four warning
messages and the "testcase ..  completed in ..." message that show up
in systemtap.log.)

Okay, I'll adjust my script.
